I'd share a personal experience: a few years ago I got the chance to fly a Boeing 737 simulator (the real thing, not the PC simulator!) At that time the only real aircraft I've flown was a Cessna 172. I managed to land on Kai TakKai Tak airport in the simulator on my very first attempt to land a (simulated) 737. I was so nervous that I totally forgot to call for the landing checklist, and the instructor helped me with the gear and flaps, but I was the sole manipulator of the controls and I landed with no automation whatsoever, not even ILS.
How? There were a few factors that came into play:
- I learnt how planes fly in ground school. Big planes fly just the same way as smaller planes, only with larger wings and more powerful engines.
- I knew how to manipulate the flight controls. It came as a bit of a surprise that the controls feel heavier than I'd expect, but they behaved the same anyway.
- My enthusiasm in aviation meant I have learnt beyond the Cessna 172 from books, online articles and PC simulation experience. I was not able to identify every single switch and knob in the cockpit, but I knew enough to fly the plane in that situation.
My answer? If it's a perfectly flyable aircraft (no failures), calm weather, then Yes, definitely! Here's what I'd do if it happens in real life:
- Aviate, navigate, communicate. No matter what happens, always remember that. That means the first thing to do after entering the cockpit is not to find the radio buttons and call for help; the first thing is to access all primary flight instruments and make sure we're flying.
- Radio for help. Declare an emergency on the last radio frequency. If no one responds, tune to 121.5 and try again.
- Request a long runway with calm weather. Unless it's something like a A380 or Boeing 747, chances are there would be a runway long enough so you don't have to worry about hitting the touchdown spot.
- Setup autoland, if available. Autoland requires suitable equipment both on the plane and on the ground. If it's not available, given a long enough final (say 20 miles), I think I'd feel comfortable hand flying the aircraft down.
- Have the emergency trucks standing by. In the event I crashed during landing, gear collapsed or whatever, everyone'd be ready to help.
